I recently installed F22 (KDE spin) from scratch on a new Dell M6800. The Live CD seems to run okay, but when I try to boot the installed OS, it freezes when I try to log in. The machine is effectively unusable as a result. Through much pain and anguish I have managed to install updates (up to date as of earlier today), to no effect. This affects login regardless of the method: graphical, tty, ssh, running 'login' from an emergency shell. If I'm lucky, TTY switching still works, but any login attempt hangs, and some take the whole system out. Only booting in emergency/maintenance/single mode works. My /var/log/messages is corrupt and contains no useful information. /var/log/boot.log has nothing obvious. The only potential clue I've seen is in dmesg: snd_hda_intel 0000:01:00.1: Enabling via VGA-switcheroo snd_hda_intel 0000:01:00.1: CORB reset timeout#2, CORBRP = 65535 The internet has some suggestions¹ that this may be the problem. There are references to adding "options snd-hda-intel enable=0,1,0" to a configuration file, but the file referenced does not exist. (¹ See https://bbs.archlinux.org/viewtopic.php?pid=1460933 for example.) Any ideas? Unfortunately it's near impossible to diagnose this because I can't have a usable shell while tickling the issue. -- Matthew -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
